For vehicles based on a van chassis with leafspring suspension, we have our standard kit, tailored exactly to the make and model of the vehicle. It includes two air bellows that sit between the axle and the chassis, at the centre of the leafspring, includes hoses connectors and valves and a compressor mounted in the vehicle to control the level/pressure. Also a dash mounted control panel with gauges and an inflate/deflate control switch for both sides. Giving you full control from the drivers seat to adjust for comfort, ride, or to raise the rear to clear an obstacle such as a ferry ramp.
